Person with Communication Challenges

I suffered a major stroke at 2008, I was 28 at work too. I got the biggest pain at my head. Trying to move myself better but I fall over straight to the floor. Blacked out at work and woke up at St Georges hospital, my family was around me at the bed. Obviously I just woke up from the operation – I tried a few times for asking a question “What happened?” but the questions sounding very unclear. 4 years later my speech is improved but a little, I can say “what happened?” now.
